DEPARTMENT
OF ELECTRICAL ENGINEERING
Degree of Bachelor of Science
in Electrical Engineering Requirements
The
course of study of the degree of Bachelor of Science in Electrical Engineering
takes five (5) academic years and one vacation school to complete and consists
of 164 semester hours. The entire program follows and includes the general education
requirements of the University of Liberia. Non-technical elective; must be in
the humanities. A foreign language known to have body of scientific and engineering
literature may be substituted for French and may also be used as a non-technical
elective if continued past the second year. Technical electives may be chosen
from upper level engineering, science or math courses but must have departmental
approval.
The
electrical engineering curriculum is firmly founded on a strong base in mathematics,
physical and engineering sciences, social science and communication skills. Nearly
half of the studies apply directly to the field of electrical engineering.
Inspection
trips to engineering work and plants are made by electrical engineering students
to supplement their theoretical studies.
Students
desiring to major in Electrical Engineering should formally request of the chairman
of the Division of Electrical Engineering admittance into the program upon his
acceptance by the College of Science & Technology. Courses in addition to
demonstrated proficiency and six (6) months of approved work experience is also
required for graduation.
